From this time, I would like to show you every nook and cranny of my personal treasure hall. First, let me guide you to the top of the piano, which, alongside dinosaurs, forms the core of my life.
The closed lid of my Yamaha C3 grand piano is covered with bone-related items such as replicas, skeletal models, and some actual fossils, centered around a rather imposing replica of an Albertosaurus skull.

The photo above shows the view from the keyboard side. The white objects in the foreground are a Moroccan turtle skull and crocodile vertebrae, followed by a Mongolian Ankylosaurus scapula (all genuine), and a Velociraptor foot replica next to them. The skeletal models include a Kaiyodo Velociraptor and Futabasaurus resin kit, a Glencoe Models Brontosaurus plastic model, a Chinese-made relief claiming to be an Archaeopteryx fossil. In front of the Albertosaurus are a T-Rex lower jaw replica and a rather crude soft vinyl skull model.

In the photo above, the three Tyrannosaurus skulls lined up are, from left to right, Sue and Stan from Black Hills, and a work by Kansai sculptor Yoshiaki Murase. The adjacent Triceratops and Pachyrhinosaurus are also by him, both wonderfully crafted but phantom items that were never commercialized. Behind the Triceratops is a relief-like skull replica of Massospondylus. The full Tyrannosaurus skeleton in the background is a Kaiyodo kit. There's also an Albertosaurus made of green origami (by Kazuya Matsumoto).

The photo above shows the view from the back of the piano. Next to the Kaiyodo T-Rex are two Glencoe Models T-Rex skeleton plastic models (one modified to a modern style). On the stand in the foreground are replicas of teeth and claws, and a Kaiyodo "Standing Triceratops." Next to it is a real caudal vertebra of a large Moroccan theropod and an Oredon skull. Hanging from the ceiling is a paper T-Rex skeleton.
As you know, a grand piano cannot be tuned without opening the lid, but with so many things on it, it's not easy to open. As a pianist, I shouldn't say this too loudly, but I haven't tuned it for over 10 years, so it's gone beyond a medieval European Pythagorean scale to a Mesozoic Pangea scale.
